Toollrwhom it may concern.

'rox, citizen of the United States, residing at Hartleyfin the county-of OBrien and State of Iowa, have inventeLLcertain new and 'usethe following is a specification.

; This invention relates to means for preventing the slipping ot' wheelsof motor vehicles, and particularly to tire-grips of that c ass using chains extending across the tire.

The, ob ect of the invention is 'to provide improved means for holding such chaiils in ful Improvements in, Tire-Grips, of which place on the tire and for fastening the same to the holding devices.

A furtherobjec't .is to provide a construction by n1eans of which the chains canbe readily takenoii or repaired, and which will not let the chains or grip sag or become loose in the wheel or catch on any part of the car, whlchls IIlJullOLlS or destructive not only to the grip but also to the tire,'and'at times to the car. The deviceyalso has advantages'of durability and cheapness, and freedom from breakage, and avoids chafing the tire.

Devices including chains for preventing slipping have'heretofore been proposed, but many have been complicated, or deficient with respect tofit, or expen'sivewith respect to original construction or to repair in' case of breakage. The devlce form ng the sub ject of this application is believed to remedy these defects, as more fully hereinafter pointed out.

panying drawings, :in which,

Figure 1 is a side elevation of awheel provided with the anti-slipping device. Fig. 2 is a cross section on the line 22 of Fig. 1.

The invention is illustrated in theaccomthe chains.

Referring specifically to the drawings, (5 indicates a wheel such as common used in anton'lobiles, and .having a pneumatic tire 7 These parts may be of any ordinary or desired-construction. I

The grip coniprises'a series of pieces of chain 8 which extend diagonally or angularly across the tire, so as to prevent circumferential slip and also lateral .skidding. These chains a1;- held on the tire by rings at the sides thereof, each ring consisting of a series of sections 9 connected together by loops 10 at the ends thereof. The sections A Specification'of Letters Patent. Application and July 7 1908'.

are 'c on'iparatively long, so as to have as few oints as possible consistentwith the application of the device to wheels of various sizes, and by reason of the few joints it will not wear out nor becdme loose as quickly as rings formed by chains having small'links. Each section is made of heavy spring steel wire and is bent to form an eye 11 at or about the middle thereof. The ends of the chains are connected to these eyes by double links 12 inade'ot' tough metal, and cold shut, and capable of being easily replaced in case, of breakage For connecting the ends of each-of the rings so-formed, in such manner that the chains can be'fitted to the wheel, and wear taken up, I provide hook devices 13 at the ends of, the ring, con nected by a short piece of chain 14'. Each of these devices has a loop 15 at one end which is hooked into the loop 10 at theend.

of the ring section, and at the other end has an oiiset or hooked part 16, terminating in a loop 17, nectedz The hook '16 extends through a link of the short chain let. I

In applying the grip to a wheel, the loop 15 at each side is unhooked from the loop 10, and the grip is laid flat along the ground. Then'the wheel of the vehicle is'run onto the grip, the ends of which are then brought up together; Then the end 15 of the hook device is passed through the 'link of the short chain-1i appropriate to draw. the ring tight-and bind the chains snugly across the to which the tread chain is cont1re. This is illustrated in Fig. 3, a nd'it.

will. be seen'that the hook device forni's' -in effect a'lever to draw the ends of the ring together, the tension being afi'orded, with respect to the loose end, by means of'the diagonal chains.

hook device 13 is turned and the link of the short chain 14 slips along to the hook 16,-

af terwhich the loop 15 canv be caught in 'the loop 10 of-the loose end section of the r111 I il case of breakage of any chain, the remainingrhains and the connections described will hold the ringslin place, and it is-not necessary to remove the whole grip. No tools are necessary to. apply or-remove the grip, and there is and-such other ,tighteners which are liable to become inoperative through rustingor -11 0 ustlnent'or operation. Wear may taken'up by detachingone of the parts l injury and which require tools or devices for ad \Vhen fully strained, thean absence ot screws.-

and moving it up to another link of the chain 14:. I claim; o A tire grip comprising, opposing side rings, each formed of sections of metal'wire interinecliatelybent to form eyesand con negated at their ends by interengaging end loops, cross chains extending between "the 'eyesof the opposite rings,oonmgectingv members at each of theends of nh rings, said members having at one of theirends loops to engage'the end ring'loops, and having at their. opposite ends hooke terminating in loops, cros's Chains extending between the latter loops of opposite rings, and short chains connecting the hooks of eachof the rings, sald connecting members bemg'movable through flheend' links of said short chains to draw their respective cross chains tight.
